Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this.
11x + 8y = 103
22x – 7y = 68

Double the first equation (on both sides) to obtain
22x + 16y = 206
Then subtract the second equation from the above (on both sides) to eliminate the variable x.
23y = 138
They solve for y.
Then use any of the original equations to solve for x.
Show your work for further assistance.

Radical 10, please don't repost questions! I took the time to solve this for you when it was already done.
